Application led May 7, 191'?, Serial No. 166,796.

T 0 all whom it may conca/fa: Be it known that we, JAMns A. CAMERON and GUsTAr B. BIRCH, citizens of the United States, and residents of the borough of Brooklyn, in the county of Kings, city and State of New York, have invented Ycertain new and useful Improvements in Slitting and Rewinding Machines, ot which the i'ollowing is a specification.

This invention relates to slitting and rewinding' machines.

In the art of slittingy and rcwinding sheet material a successful type of machine ein#` bodies the mechanism shown in Patent llo. 1,076,189, in which a pair ot rewindinr rolls supports the rewound coils and cooperates with a third roll engaging the upper periphery of the coils to rotate the coils and there'- by perform the rewinding operation. in this ,type ot machine one of the rewinding rolls on which the rewound coils are supported is utilized also as a cutter roll and for this purpose is provided with a shell made up of cylindrical sections having' a glass-hard surface. Because of the great ditlieulty of uniformly and properly harden ing the surface ot a section having` a large diameter, it has been found necessary to restrict as tar as possible the diameters oi' the sections. l/Vith the development oi the art, however, a point has been reached in 'which a cutter roll having a diameter small enough to comply with the limitations oi' the hardening' process can not be used as a supportingr roll for the rewound coils because of its tendency to bend under the weight of the coils and thereby interfere with both the slitting' and the rewinding operations. in the cri-pending' application Serial No. 146,569 there is shown a construction oi' slitting` and rewindingr machine in which a cutter roll ot relatively small diameter is provided, which does not engage the rewound coils, but, instead, is mounted in the tramework of the machine beneath a pair of rewinding' rolls of relatively large diameter.

The main object of this invention is to provide means for so mounting' the cutter roll in the body of the machine that access can be had thereto to remove 'or replace the roll in whole or in part without dismantling; the machine framework.

With this and other objects in view 'the in` vent-ion consists principally in proi'iding one Specification of Letters Patent.

of the machinel frame members with an A,opening` through which the cutter roll can be passed and in making use of a bearing member for supporting` one end or the cutter roll shaft in said opening.

Other features oi' theinvention will be referred to as the specii'ication proceeds.

In the particular embodiment of the invention disclosed, coil supporting rewinding rolls ot relatively large diameter are employed a nd, in lieu ot adapting' one of these rolls to serve also as a critter roll, a special cutter' roll is provided, as in application Serial No. 146,569, which` serves only as a cutter roll and takes no'part in the rewinding operation. The cutter roll is preferably mounted beneath'and intermediate the rewinding' rolls with its ends journaled within the boundaries of the heavy framework of the machine and, in order to provide access to the cutter roll tor any purpose, such as the replacement of the roll in whole or in part vithout dismantling' the machine framework, one ot the frame members in et the cutter roll shaft is constructed to eX- tend beyond the framework oi' the machine;

.produced by the pull on the web 'l1 as it passes around the rewinding roll 2 and is fed directly to the periphery or" the re- Wound coils 3. rfhe rewind shaft 5 forms a core for the rewound coils and is so mounted in the machine that it is free to rise as the diameters of the coils increase. The coil supporting rolls l and 2 are rotated in the same direction and cooperate with a driven top rewinding roller 6, rotating in the same direction and bearing against the upper surface of the rewound coils 3, to rotate the interposed coils. The roller 6 is preferably journaled in carriages i' that are adapted to move upwardly along the vertical guide members 8 in accordance with the increase in size et' the rewound coils.

The slitting mechanism preferably romprises the cutter roll l0, having its ends mounted in the end pieces il? ot the machine framework. is will be seen the cutter roll is mounted beneath and intermediate the rc- Winding` rolls l and 53, where it cooperates with the cutting disks l2 te slit the web ot.' material t.

'n the practice ot' the invention the cutter roll l() is provided with a hardened enter shell made up of sections Sl and, in order to malte it possible to replace the ring sections as they .become Worn, as well as to bodily remove the cutter roll for any reason. without disn'iantling` the machine traine-work. one ot the frame pieces 37 is preferably prorided 'with an opening l5 ot sullicieut sire togive access to the cutter roll and permit the passage therethrough of the cutter sections S) or oit the cutter roll l() itsel l'. A ren'iovable bearing member 36 is adapted to be bolted to one oi the .trame pieces 3T and to project into the opening 45 to di rectly support the end ot the cutter roll shaft. Temporary supporting' means fior the cutter roll, such as lifting jacks, can be made use of l'or sustaining the weight of the roll While the bearing' member 256 or the ring` sections 9' are beinpr removed.

Advantage is taken of the tact that the cutter roll l() is mounted directly beneath the top rewinding' roller o, to provide driving connections through which the roller o can be driven directly from the cutter roll shaft. Fory this purpose the cutter roll shaft extends beyond `the irameworlc ot themachine as 'is indicated at 58 in Fig. 2 ot the dra-Whig.

The drivingA connection bctwecn the top rerrindiu; roller o and the extended portion of the cutter roll sha'it includes a bevel Igear 5l mounted on the shaft oi' the rexfindinp roller o', which meshes with a, corr winding; bei/cl gear 52 journaled in a. bracket :'33 at tached to one ot the carriages 'Y'. ifi splined Vertical. drive shaft journaled at the lower end in a bracket 55 extei'ulinp ont@ Wardly from the machine trameworli` is so related to the bevel rear that the gear free to slide vertically along', but is caused to turn with the drive shalt oel and is adapted to be driven by the shaft 5l in any position which the rewinding roller t* may take because of the increasing diameters of the reivound coils. the drive shaft 5l is rotated through a bevel pinion 56 meshing; with a bevel gear 57, mounted to rotate on the shalt 5S ol the cutter roll ll).

` ,ln order to vary the speed oli rotation ot tie top rewinlfling roller l to most etliew tively Wind different materials. the bevel gear 5T is driven through a 'friction clutch from the extension 55% oi the cutter roll shalit. This clutch. includes the r i? the frictionally driven ring-,f t tively driven. rings o0, and driven member Gt, which spl the cutter roll shait extern) f'l. carries pins T5 that extend into openin the rings (Si). l1a1u,l.;lice.l ,(33. altnrhcd to a sleeve Gil which is mounted. to rotate the end of the braifket i i raryin'p; the eliecti'reue. n c

the clutch to thereby control he rotation of the gear 57 and conseqr nitly ot the top rewinding` roller o.

The sleeve bei threaded at one cud te `give motion to a correspoiulingly threaded collar G5 secured against rotation by a pin no proie np; into, and free to slide in` an opening o7 in the lower end ol tl'ie bracket Il spring 38 interposiwl between the collar and an abutment member free to slide on the shalt 53, conveys motion from the collar G5 to the clutch member lll7 as will be obvious. A thumb-sere. 'TO is used to tix the pin 6G and, hence, the collar o5 in any 7l in the shaft means for applying lubricant ingr parts mounted thereon.

For insuring 'the complete end 58 provides a convenient to the rotatseveranee ot he web and the separation et the strips,

`t lil in il l of the' dra-wing, are employed. This separatine member consists oi' a blade pivotally mounted in'a bracket sliilably mounted on the supporting bar and adapted to be locked in any desired location by means et the thumb screw 2l'. i etal mounting ol the sepa-.rating blai cilitates the threadingr et the web, si arrangement permits the blades to be to a position in which they u'ill not int,e the 'web streti'fh while the threading; op tion being carried out.
